Cannabidiol regulates behavioural alterations and gene expression changes induced by spontaneous cannabinoid withdrawal, Francisco Navarrete et al., 2018

Cannabidiol regulates behavioural alterations and gene expression changes induced by spontaneous cannabinoid withdrawal Francisco Navarrete, Auxiliadora Aracil-Fernández and Jorge Manzanares British Journal of Pharmacology, 2018. Doi : 10.1111/bph.14226   BACKGROUND AND PURPOSE Cannabidiol (CBD) represents a promising therapeutic tool for treating cannabis use disorder (CUD). This study aimed to evaluate the effects of CBD on the behavioural and gene expression alterations induced by spontaneous cannabinoid withdrawal. EXPERIMENTAL APPROACH Spontaneous cannabinoid withdrawal was evaluated 12 h after cessation of CP-55,940 treatment (0.5 mg·kg1 every 12 h, i.p.; 7 days) in C57BL/6J mice. The effects of CBD (5, 10 and 20 mg·kg1, i.p.) on withdrawal-related behavioural signs were evaluated by [...]

Addiction au cannabis, confinement et détention, Jean Michel Delile et al., Fédération Addiction, mars 2020

Addiction au cannabis, confinement et détention Jean Michel Delile, David Saint Vincent, Laurent Michel, Patrick Veteau Fédération Addiction, mars 2020 Cannabis et dépendance Longtemps, beaucoup ont pensé que le cannabis n’était pas une drogue (dangereuse), ou alors seulement une drogue « douce », au sens où il n’entrainait pas de syndrome physique de manque, à la différence de l’alcool, des opiacés ou des benzodiazépines… Il a fallu beaucoup de temps aux usagers et aux médecins pour réaliser que l’évidence de la souffrance des patients démontrait que la clef de l’addiction en tant que trouble était plus dans le désir/besoin irrépressible de consommer que dans [...]

Cannabis and cannabinoid drug development: evaluating botanical versus single molecule approaches, Marcel O. Bonn-Miller et al., 2018

Cannabis and cannabinoid drug development: evaluating botanical versus single molecule approaches Marcel O. Bonn-Miller, Mahmoud A. ElSohly, Mallory J. E. Loflin, Suman Chandra and Ryan Vandrey International Review of Psychiatry, 2018, VOL. 30, NO. 3, 277–284 Doi : 10.1080/09540261.2018.1474730   ABSTRACT Accumulating evidence suggests that the endocannabinoid system is a promising target for the treatment of a variety of health conditions. Two paths of cannabinoid drug development have emerged. One approach is focused on developing medications that are directly derived from the cannabis plant. The other utilizes a single molecule approach whereby individual phytocannabinoids or novel cannabinoids with therapeutic potential are identified and synthesized for pharmaceutical [...]

Cannabidiol attenuates haloperidol-induced catalepsy and c-Fos protein expression in the dorsolateral striatum via 5-HT1A receptors in mice, Andreza B. Sonego et al., 2016

Cannabidiol attenuates haloperidol-induced catalepsy and c-Fos protein expression in the dorsolateral striatum via 5-HT1A receptors in mice Andreza B. Sonego; Felipe V. Gomes; Elaine A. Del Bel; Francisco S. Guimaraes Behavioural Brain Research, 2016, 21. Doi : 10.1016/j.bbr.2016.04.042   Highlights  Cannabidiol (CBD) attenuated haloperidol-induced catalepsy.  CBD reduced c-Fos protein expression in the dorsal striatum induced by haloperidol.  CBD effects were blocked by 5-HT1A receptor antagonist.   Abstract Cannabidiol (CBD) is a major non-psychoactive compound from Cannabis sativa plant. Given that CBD reduces psychotic symptoms without inducing extrapyramidal motor side-effects in animal models and schizophrenia patients, it has been proposed to act as an atypical antipsychotic. In addition, CBD [...]

Unique treatment potential of cannabidiol for the prevention of relapse to drug use: preclinical proof of principle, Gustavo Gonzalez-Cuevas et al., 2018

Unique treatment potential of cannabidiol for the prevention of relapse to drug use: preclinical proof of principle Gustavo Gonzalez-Cuevas, Remi Martin-Fardon, Tony M. Kerr, David G. Stouffer, Loren H. Parsons, Dana C. Hammell, Stan L. Banks, Audra L. Stinchcomb and Friedbert Weiss Neuropsychopharmacology, 2018, 43, 2036–2045. Doi : 10.1038/s41386-018-0050-8   Cannabidiol (CBD), the major non-psychoactive constituent of Cannabis sativa, has received attention for therapeutic potential in treating neurologic and psychiatric disorders.
